Abstract

The invention relates to a method of producing a formed cellulosic article dyed using a vat dye, in particular a fibre or a film, comprising the following steps: providing a cellulosic starting material which comprises the vat dye in molecularly disperse form; preparing a formable solution from the cellulosic starting material; forming the solution through a suitable forming tool; precipitating or regenerating the cellulose from the formed solution.
